Flashcards in Chapter 3 - Thoracic and Ribs Deck (26):
1

Location of spinous processes in thoracics...

T1-3 = at the level
T4-6 = 1/2 segment below
T7-9 = 1 segment below
T10 = 1 segment below
T11 = 1/2 segment below
T12 = at the level

2

Spine of scapula - level

T3

3

Inferior angle of scapula - level

T7 SP (so T8 body)

4

Sternal notch - level

T2

5

Sternal angle - level

Attaches to what?

T4

Rib 2

6

Nipple - dermatome

T4

7

Umbilicus - dermatome

T10

8

Main movement of upper/mid thoracics
Main movement of lower thoracics

Rotation
F/E (like lumbars)

9

Attachments of the diaphragm

Xyphoid process
Ribs 6-12
Bodies and intervertebral discs of L1-L3

10

Intercostals - actions (2)

Elevate ribs in inhalation
Prevent retractions during inhalation

11

2 primary muscles of respiration

Diaphragm
Intercostals

12

Secondary muscles of respiration (5)

Scalenes
Pectoralis minor
Serratus anterior and posterior
Quadratus lumborum
Latissimus dorsi

13

Typical ribs

What makes them typical?

3-10

Head, neck, tubercle, angle, shaft
Articulate w/ corresponding vertebrae and one above

14

Atypical ribs

Why?

1, 2, 11, 12

1 = articulates w/ T1 only, no angle
2 = large tuberosity on shaft for serratus anterior
11/12 = no tubercles, only articulate w/ their vertebrae

15

True ribs

Why?

1-7

Attach to sternum directly via costal cartilage

16

False ribs

How are ribs 8-10 attached?

8-12 (do not attach directly to sternum)

Their costal cartilage to the cartilage of the one above

17

Floating ribs

11, 12

18

Primarily pump handle

In what plane?
Around what axis?

1-5

Sagittal plane
Transverse axis

19

Primarily bucket handle

In what plane?
Around what axis?

6-10

Coronal plane
A-P axis

20

Primarily caliper motion

In what plane?
Around what axis?

11, 12

Transverse plane
Superior-inferior axis

21

Bucket handle - superior or inferior during inhalation?

SUPERIOR

22

Inhalation dysfunction - pump handle...

Movement that occurs?
Intercostal narrowing?
Prominent edge?
Tenderness and TTCs?

Cephalad on inspiration is OK

Anterior narrowing above the rib

Superior edge of posterior rib angle is prominent

TTCs @ CC junction, CS junction, posterior rib angles

23

Inhalation dysfunction - bucket handle...

Movement that occurs?
Intercostal narrowing?
Prominent edge?
Tenderness and TTCs

Lateral part moves cephalad on inspiration

Lateral narrowing above the rib

Lower edge of rib shaft is prominent

TTCs @ intercostal mm at mid-axillary line, posterior rib angles

24

Exhalation dysfunction - pump handle...

Intercostal narrowing?
Prominent edge?
Tenderness and TTCs

Anterior narrowing below the rib

Lower edge of posterior rib angle is prominent

TTCs @ CC jxn, CS jxn, posterior rib angles

25

Exhalation dysfunction - bucket handle...

Intercostal narrowing?
Tenderness and TTCs

Lateral narrowing below the rib

TTCs @ intercostal mm at mid-axillary line, posterior rib angles

26

Inhalation dysfunction...treat which rib?

Exhalation dysfunction...treat which rib?

Lowest rib

Highest rib
